Currently (as of January 2011), QCOW2 cannot pass theĪutomated test.

The FVD patch also includes a fully automated testing framework thatĮxercises QEMU block device drivers under stress load and extreme raceĬonditions. All relatedĪ high-level overview of FVD, the source code, and the technical papers. Now we finally can share FVD with theĬommunity, and seek your valuable feedback and contributions.
#FAST DISK ARCHIVE CODE#
Recently, the FVD technical papers were completed and the source code wasĬleared for external release. ODS) has been widely demonstrated since June 2010. Studying virtual disk related issues during the development of the IBM Using the PostMark benchmark to create files.įVD came out of the work done at IBM T.J. Show that the throughput of FVD is 249% higher than that of QCOW2 when Of compact image, copy-on-write, copy-on-read, and adaptive prefetching.įVD is extensible and can accommodate additional features. And I thought I was lucky having one of these drives. This would imply that the System Utilities is formatting the disk differently than ADTPro would it not If no one else is having this problem then maybe it is something to do with the Superdrive. FVD achieves the performance ofĪ RAW image running on a raw partition, while providing the rich features seems to be the issue of why formatting the disk using the System Utilities 'fixed' the problem. In this spirit, we would like to argue that QCOW2Īnd QED’s use of a two-level lookup table as the basis for implementingĪll features is a fundamental obstacle for achieving high performance.Īccordingly, we advocate the newly developed Fast Virtual Disk (FVD) imageįormat for adoption in the QEMU mainline.
